Gold-plated jewelry offers a beautiful and affordable alternative to solid gold pieces. However, one common concern with gold-plated jewelry is its susceptibility to tarnishing over time. Tarnishing can dull the shine and luster of your favorite jewelry, diminishing its appeal. To ensure your gold-plated pieces retain their brilliance and charm, it's essential to take proper care and implement preventive measures.

In this comprehensive guide, we will explore effective tips to stop gold-plated jewelry from tarnishing, helping you maintain its radiant beauty for years to come.

I. First, what is Jewelry Tarnish?

Jewelry tarnish is a natural process that occurs when the surface of metal jewelry becomes discolored or dull over time. It is most commonly seen in metals like silver, copper, brass, and even gold-plated jewelry. Tarnish forms when the metal reacts with substances in the environment, such as oxygen, sulfur, moisture, and certain chemicals.

The primary cause of tarnishing is oxidation. When metal jewelry is exposed to air and moisture, a chemical reaction occurs, resulting in the formation of a thin layer of metal oxide on the jewelry's surface. This layer is what gives the jewelry its tarnished appearance.

Tarnish can take on various colors, depending on the metal involved. For example, silver jewelry may develop a blackish or yellowish tint, while copper and brass jewelry may turn brown or green. Gold-plated jewelry can also tarnish, with the underlying base metal becoming visible when the gold layer wears off.

It's important to note that tarnish is a surface phenomenon and does not affect the core integrity of the metal. While tarnished jewelry may lose its luster and shine, it can often be restored to its original beauty through proper cleaning and maintenance.

II. Understanding Gold-Plated Jewelry:

Gold-plated jewelry is created by applying a thin layer of gold onto a base metal, such as brass or silver, through a process called electroplating. The gold layer adheres to the base metal, resulting in a stunning gold appearance without the high cost of solid gold. While gold plating offers excellent aesthetics, the thin gold layer is susceptible to wear and tear, leading to tarnishing over time.

III. Why Gold-Plated Jewelry Tarnishes:

Tarnishing occurs when the surface of the gold-plated jewelry reacts with oxygen, moisture, and certain chemicals. The metal beneath the gold layer can gradually oxidize and discolor, leading to a loss of luster and shine. Various factors contribute to the tarnishing of gold-plated jewelry:

  1. Chemical Reactions and Tarnishing: Tarnishing occurs when the metal in gold-plated jewelry reacts with substances in the environment. Chemicals present in household cleaning products, perfumes, lotions, and some cosmetics can create an unfavorable environment for the gold layer, causing it to deteriorate.

    Household Cleaning Products: Many household cleaners contain harsh chemicals like bleach, ammonia, and acids, which can be particularly damaging to the delicate gold layer. Cleaning solutions can break down the protective layer of gold, leading to tarnishing and dullness.

    Perfumes and Lotions: Some perfumes and lotions may contain chemicals that react with the metal in gold-plated jewelry. When these products come into contact with the jewelry, the chemical reaction can cause the gold layer to wear off, exposing the base metal and resulting in tarnish.

    Cosmetics: Certain cosmetics, especially those containing sulfur or harsh ingredients, can have adverse effects on gold-plated jewelry. When makeup or skincare products come into contact with the jewelry, they can contribute to the breakdown of the gold layer, leading to tarnishing over time.

  2. Moisture and Humidity: Oxidation:  

a. Oxidation: Moisture in the air contains oxygen, and when the metal in gold-plated jewelry comes into contact with oxygen, it undergoes a process known as oxidation. This chemical reaction can cause the metal to form metal oxides, leading to tarnish on the jewelry's surface.

b. Electrolysis: In humid environments, the moisture in the air can act as an electrolyte, facilitating an electrochemical reaction between the gold layer and the base metal. This process can accelerate the breakdown of the gold layer and lead to tarnishing.

c. Corrosion: High humidity levels can also increase the chances of corrosion in the metal of the base layer. Corrosion can weaken the metal's protective barrier, making it more susceptible to tarnish and other forms of damage.

    3. pH Levels: The acidity of an individual's skin can also influence the rate of tarnishing. More acidic skin types may lead to faster oxidation of the metal beneath the gold layer. 

IIII. How Thick is the Gold Plating on Jewelry? Why Does it Matter?

The thickness of gold plating on jewelry can vary widely depending on the manufacturer, the specific piece of jewelry, and its intended use. As mentioned earlier, gold plating is typically measured in microns or mils. The most common thickness ranges for gold plating on jewelry are:

  1. Light Gold Plating: This is usually around 0.5 to 1 micron (20 to 40 micro-inches) thick. It's commonly used in fashion jewelry or costume pieces.
  2. Standard Gold Plating: This ranges from 1 to 2 microns (40 to 80 micro-inches) in thickness and is more durable than the light plating option.
  3. Heavy Gold Plating: This can be between 2 to 5 microns (80 to 200 micro-inches) thick, providing increased durability and tarnish resistance.

Now, let's talk about how the thickness of gold plating relates to tarnishing. Thicker gold plating generally offers better protection against tarnishing compared to thinner plating. Tarnishing is a natural process that occurs when certain metals, like copper or silver in the base metal, react with elements in the environment, such as oxygen and sulfur compounds. This chemical reaction can lead to discoloration and dullness of the jewelry.

Thicker gold plating creates a more robust barrier between the base metal and the environment, making it less susceptible to the tarnishing process. It provides an additional layer of protection against exposure to moisture, air, and chemicals, which can accelerate tarnishing. So, make sure to choose the thickest plating possible when shopping.

V. Effective Tips to Prevent Tarnishing:

  1. Remove Before Water Activities: To protect your gold-plated jewelry from tarnishing, remove it before swimming, showering, or engaging in water-related activities. Chlorinated water and salt water can be particularly damaging to the gold layer.
  2. Avoid Harsh Chemicals: Remove gold-plated jewelry before using household cleaning products or any chemicals that may come into contact with the jewelry. Be cautious with perfumes and lotions, as they can contain chemicals that may cause tarnishing.
  3. Clean Gently: To clean gold-plated jewelry, use a soft, lint-free cloth to gently wipe away dirt and oils. Avoid using harsh cleaning agents or abrasive materials that may scratch the gold layer.
  4. Dry Completely: After cleaning or exposure to moisture, ensure your gold-plated jewelry is completely dry before storing it. Moisture can accelerate tarnishing, so keeping the jewelry dry is crucial.
  5. Apply a Protective Coating: Consider applying a clear nail polish or jewelry sealant to the areas of the jewelry that come into direct contact with your skin. This can act as a protective barrier and slow down the tarnishing process.
  6. Limit Contact with Skin Oils: While tarnishing is a natural process, limiting the contact of your gold-plated jewelry with skin oils can help slow down oxidation. Remove jewelry before sleeping to reduce contact with natural oils produced by your skin.
  7. Professional Inspection: Periodically have your gold-plated jewelry inspected by a professional jeweler. They can assess the condition of the gold layer and address any signs of wear or damage.
